Blockchain
Web3, smart contracts, and specialized crypto tools.
php-full-stack-developer
A senior, governance-backed PHP full-stack delivery OS for OpenClaw. Emphasizes pre-flight analysis, safe data changes, explicit contracts, and reproducible verification.
warren-deploy
Deploy websites and files permanently on MegaETH blockchain. AI agents stress test the network by deploying HTML on-chain using SSTORE2 bytecode storage. Agents pay their own gas.
settlement-witness
OpenClaw skill: fetch replay-stable PASS/FAIL receipts from the public SettlementWitness HTTPS endpoint. Stateless. Deterministic. Signed.
jb-suckers
Juicebox V5 sucker contracts for cross-chain token bridging. Use when: (1) implementing bridge functionality, (2) understanding prepare/toRemote/claim flow, (3) working with merkle proofs for cross-chain claims, (4) querying sucker pairs from registry, (5) handling emergency exits, (6) debugging "claimable" vs "pending" states, (7) encoding sucker transaction calldata. Covers JBSucker, JBOptimismSucker, JBArbitrumSucker, JBCCIPSucker, and JBSuckerRegistry.
jb-hook-deploy-ui
Deploy custom Juicebox hooks from browser. Compile Solidity, deploy contracts, verify on explorers, and attach to projects. Works with Claude-generated hooks.
jb-explorer-ui
Etherscan-like contract explorer for Juicebox projects. Read contract state, write transactions, and decode events.
jb-cash-out-hook
Generate custom Juicebox V5 cash out hooks from natural language specifications. Creates Solidity contracts implementing IJBCashOutHook and/or IJBRulesetDataHook with Foundry tests. First evaluates if off-the-shelf solutions (721 hook, Revnet) fit the use case.
cheese-agent-marketplace
Create, browse, accept, and complete on-chain work requests. Agents can act as requesters (posting jobs) or providers (completing work). Uses ETH/stablecoin escrow on Base network.
8004-agent
8004 Agent Skill for registering AI agents on the ERC-8004 Trustless Agents standard and authenticating them via SIWA (Sign In With Agent). Use this skill when an agent needs to: (1) create or manage an Ethereum wallet for onchain identity, (2) register on the ERC-8004 Identity Registry as an NFT-based agent identity (SIGN UP), (3) authenticate with a server by proving ownership of an ERC-8004 identity using a signed challenge (SIGN IN / SIWA), (4) build or update an ERC-8004 registration file (metadata JSON with endpoints, trust models, services), (5) upload agent metadata to IPFS or base64 data URI, (6) look up or verify an agent's onchain registration. The agent persists public identity state in MEMORY.md. Private keys are held in a separate keyring proxy server — the agent can request signatures but never access the key itself. Triggers on: ERC-8004, trustless agents, agent registration, SIWA, Sign In With Agent, agent identity NFT, Agent0 SDK, agent wallet, agent keystore, keyring proxy.
contract-template
Generate smart contract templates using Accord Project - legally enforceable, machine-readable
arbitrum-dapp-skill
Opinionated guide for building dApps on Arbitrum using Stylus (Rust) and/or Solidity. Covers local devnode setup, contract development, testing, deployment, and React frontend integration with viem. Use when starting a new Arbitrum project, writing Stylus or Solidity contracts, deploying to Arbitrum, or building a frontend that interacts with Arbitrum contracts.
typhoon-starknet-account
Create a Starknet account to your agent through Typhoon anonymous deployer and interact with Starknet contracts (read/write + preflight).
skill-vetting
Vet ClawHub skills for security and utility before installation. Use when considering installing a ClawHub skill, evaluating third-party code, or assessing whether a skill adds value over existing tools.
walletconnect-agent
Enable AI agents to autonomously connect to Web3 dApps via WalletConnect v2 and automatically sign transactions. Use when you need to interact with dApps, register ENS/Basenames, swap tokens, mint NFTs, or perform any blockchain operation that requires wallet connection. Supports Base, Ethereum, and other EVM chains.
arb-injection
BYOCB ArbInjectionSkill: Scan EVM smart contracts for arbitrary call injection vulnerabilities. Monitor chains in real-time or scan specific addresses.
audit
Deep EVM smart contract security audit system. Use when asked to audit a contract, find vulnerabilities, review code for security issues, or file security issues on a GitHub repo. Covers 500+ non-obvious checklist items across 19 domains via parallel sub-agents. Different from the security skill (which teaches defensive coding) — this is for systematically auditing contracts you didn't write.
legacy-testimony
Advanced Dead Man's Switch for Agents. Securely encrypts and delivers passwords, files, crypto assets, and messages to designated contacts if you fail to check in. Features Blockchain Notarization, Self-Destruct, Ghost Agent, and Public Blast.
etherscan-verification
Verify smart contracts on Etherscan-compatible block explorers. This skill should be used when the user asks to "verify contract", "verify on etherscan", "verify on chain scan". Handles standard verification, Etherscan V2 API for unsupported chains on foundry, proxy patterns, and factory-created contracts.
build-smart-contracts
Build Algorand smart contracts using Algorand TypeScript (PuyaTs) or Algorand Python (PuyaPy). Use when creating new smart contracts from scratch, adding features or methods to existing contracts, understanding Algorand contract development patterns, or getting guidance on contract architecture. Strong triggers include "create a smart contract", "write a contract that...", "build a voting contract", "implement an NFT contract", "add a method to the contract".
export-controls
Use when identifying export control and sanctions laws that affect software distribution and encryption. Covers US EAR and ITAR, EU Dual-Use Regulation, Wassenaar Arrangement, OFAC sanctions, and encryption export rules that apply to software products distributed internationally. USE FOR: export controls, EAR, ITAR, OFAC sanctions, Wassenaar Arrangement, encryption export, ECCN, dual-use technology, embargoed countries, deemed exports, open-source encryption exemptions DO NOT USE FOR: implementing encryption (use security/cryptography), trade secret protection (use intellectual-property), general international business law (consult trade counsel)
azure-compliance
Comprehensive Azure compliance and security auditing capabilities including best practices assessment, Key Vault expiration monitoring, and resource configuration validation. USE FOR: compliance scan, security audit, azqr, Azure best practices, Key Vault expiration check, compliance assessment, resource review, configuration validation, expired certificates, expiring secrets, orphaned resources, policy compliance, security posture evaluation. DO NOT USE FOR: deploying resources (use azure-deploy), cost analysis alone (use azure-cost-optimization), active security hardening (use azure-security-hardening), general Azure Advisor queries (use azure-observability).
